T 0 all whom it may concern:

.Be it known that I, JOHN O'r'ro Hansen, J r. a citizen ofthe UnitedStates of America, l

residing at Detroit, in the countyof \Vayne, State of Michigan, haveinvented certain new and useful Improvements in Rotary- Valves forExplosion-Engines,of which the following a specification, referencebeing had therein to the accompanying drawingsqij The lnventionrelatesto explosion engines I of that type employingfrotary valves",andthe invention consists'in the peculiar con.

struction of the 'Ivalve and the construction and arrangement of: -thesame; in relation to the explosion engine as hereinafter set forth.

In the drawings Figure 1 is a,'vertical' cross section through anexplosion engine to which "the improved construction of valve isapplied. Fig. 2' is a section on line we 'j s a: sectiononl li n Fi 1. aI

' is the; engine casing which may if be' either a single cylinder or. aplurality 'of'in-' tegral, multiple cylinders; B is the cylinder head;and C are'rotary; valves. in'said head extending [transversely thereof,and fcon-.

trolling inlet and exhaust port"s -D. and E; The valve C is preferablyin the form of a hollow sleeve, which has portsfF 'andF'. forregistration respectively with theports D and Within .the sleeve is a no n-rota-' tive sleeve or hollow coremember H, which vis correspondinglyported. and which corn-v municates through its outer end with the inletmanifold or exhaust. I Asshown this hollow core memberis formed in twosec-' tions'H and H, extending inward from opposite ends of the hollowsleeve C, and having'flanges H for overlapping the ends of sa1d sleevesand forming agas-tight joint therewith. The inlet manifold I and ex= halsli' conduit J are secured tothe engine" casing so as tocOm'munioatewith the holy low core members asisho'wn inF g. 1.

Surrounding the hollow sleevegvalve' is a valve case K, while the latteris surrounded by a water-jacket L,also"formed in the head t B. At thetop of the head is a longitudinal channel in whichv is located a rotaryshaft M having a spiral gear N thereon, and which is in mesh with a.correspondin spiral gear 0 upon the rotarysleeve C... hus all of thevalves may be simultaneously driven in proper timed relation, while thechannel I Specification of Letters Patent.

Q is a cap arranged above the head B, and

which is preferably hollow and-may be convcniently used as a-lubricantstorage rece tacle.-

Vith the construction as described in op- "eration, the valve ()Willcontrol the ports I): and E and in their closed position will Qform'ajdouble seal. by-reasoniof. the bearing on the innerv core member H. aswell as that upon-the outer valve case K. \Vhen the.- va'l've issubjected to the pressure of gas Within the; explosion; chamber it will.be

The sections H and H of the core members areprovided with heads at theirinner ends, .which separate the exhaust conduit from the inlet, and topermit of'adjustment :tor taking up the wear these sections arepreferably-clamped together by a bolt- R.

, Wh'atlclaim as my invention is:

'1.- Inan e'xplosion engine, the combina- Qtion with a'rotary,ported'sleeve-valve, of a hollow core'member formed of a plurality Offsections ,insertible from opposite endsof the rotary"valve, ;said, valvebeingseated on said core member and said plurality of core sectionshaving their inner adjacent ends secured together. t

2. In an explosion engine the combination with the engine cylinder; of arotary hollow, ported sleeve-valve extending transversely 1 tighter litto the inner core memberll,

of sa'id'cylinder, a hollow ported core within said sleeve, inlet andexhaust conduits connected. with said engine cylinder at opposite endsof 'said'hollow core, and means centrally "engaging said rotary sleevefor driving the same.-

Inan'explosion engine the combination with the engine casing, having atransmeans engaging said valve intermediate its ends for driving thesame.

6. An explosion engine compr sing the ena detachable head for saidcylinder, having a transversely extending cylindrical valve casetherein, aqrotary ported sleeve valve within said case, inlet andexhaust conduits communicating with the 'opposite' ends of said valve,'adrive shaft extendmg transversely of the axis of saidsleeve valvearranged in a groove'in the 1 upper portion of said head, intermeshing30 spiral gearson said shaft and said sleeve, and a cap for inclosingsaid shaft.
